Archaized brick with low sintering temperature, low radioactivity and ultrawhite whole body, green body and preparation method of green body

Abstract

The invention discloses an archaized brick with a low sintering temperature, low radioactivity and a ultrawhite whole body, a green body and a preparation method of the green body. The archaized brickcomprises a green body, ground glaze and cover glaze. On the basis of a situation that a traditional archaized brick production technology is free from significant changes, the key point is that production raw materials are selected, the formula composition of the green body is regulated and optimized, a sintering technology is regulated and optimized, so that the prepared archaized brick producthas the characteristics of low sintering temperature, low radioactivity, high whiteness and good decoration effect and the like. Meanwhile, the technology has higher universality and is easy in popularization in industries. The invention also relates to a green body of the archaized brick with the low sintering temperature, the low radioactivity and the ultrawhite whole body, and a preparation method of the green body.

Description

Technical field: [0001] The invention relates to the technical field of preparation of glazed tiles, in particular to a whole-body ultra-white antique tile with low firing temperature and low radioactivity, a green body and a preparation method thereof. Background technique: [0002] With the development of ceramic tile decoration technology, porcelain antique tiles have become popular in domestic and foreign markets in recent years. The cultural and historical connotations and rich decorative techniques contained in the antique bricks make them become the mainstream products of ceramic tiles in the European and American markets, and they have also developed rapidly in China. Antique bricks have a wide range of applications, and have now developed into wall-floor integrated tiles. Their innovative design and innovative technology endow antique bricks with higher market value and vitality. [0003] Antique bricks usually refer to glazed decorative bricks, the glaze is mainly...

Problems solved by technology

In the prior art, it is difficult to adjust the preparation process of antique bricks beyond 1180°C, mainly because it is easy to cool down, but it is difficult to ensure the production performance and quality of antique bricks. The main problems are as follows: (1) In order to reduce the temperature of firing Temperature, the amount of clay raw materials added in the ceramic formula is small, so that the strength of the green body is not enough, and the green body is easy to break; (2) In order to reduce the firing temperature and shorten the firing cycle, a large amount of flux raw materials are introduced into the formula, It makes the product prone to defects such as deformation during firing, and may cause kiln jam accidents in severe cases; (3) The introduction of a large amount of flux raw materials makes the strength of the low-viscosity glass phase in the product low. When firing and cooling, due to internal stress (4) The existence of a large number of glass phases in the product greatly increases the brittleness of ceramic tiles and reduces the thermal shock resistance and strength of ceramic tiles; (5) Low-temperature raw materials such as potassium albite feldspar are more expensive , generally used in fabrics or glazes, the introduction of a large number of such raw materials in the blank will greatly increase the cost of the formula, which is unacceptable for enterprises aiming at profit; (6) The introduction of low-temperature flux materials makes ceramic tiles The firing temperature range narrows, which is not conducive to stable production; (7) The potassium and sodium content in the formula is high, and the chemical corrosion resistance of the product is poor
